[iOS] Header visible when more than 5 screens present

Comienza ejecutando el ejemplo reproducible enlazado de FormSheetBug con react-native-bottom-tabs 0.9.0 y, después, inspecciona la implementación del navegador de pestañas para comprobar cómo gestiona las pestañas ocultas y las pantallas posteriores a la quinta. Reproduce el caso de seis pantallas, navega a la sexta pantalla oculta y verifica que no aparezca ningún encabezado de botón de retroceso "More".

Before submitting a new issue

• I tested using the latest version of the library, as the bug might be already fixed.
• I tested using a supported version of react native.
• I checked for possible duplicate issues, with possible answers.
